I am having an issue with opensips crashing. I have reviewed the guide on how to generate a core dump. My current problem is when I try to use gdb.<br><br>Here is what I am doing:<br> <br> gdb /usr/sbin/opensips core.opensips.993.b6ac8a71177a49cd8238e22ba265c6e9.16129.1594410164000000.lz4<br><br>GNU gdb (GDB) Red Hat Enterprise Linux 8.2-11.el8<br>Copyright (C) 2018 Free Software Foundation, Inc.<br>License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html><br>This is free software: you are free to change and redistribute it.<br>There is NO WARRANTY, to the extent permitted by law.<br>Type "show copying" and "show warranty" for details.<br>This GDB was configured as "x86_64-redhat-linux-gnu".<br>Type "show configuration" for configuration details.<br>For bug reporting instructions, please see:<br><http://www.gnu.org/software/gdb/bugs/>.<br>Find the GDB manual and other documentation resources online at:<br> <http://www.gnu.org/software/gdb/documentation/>.<br><br>For help, type "help".<br>Type "apropos word" to search for commands related to "word"...<br>Reading symbols from /usr/sbin/opensips...Reading symbols from .gnu_debugdata for /usr/sbin/opensips...(no debugging symbols found)...done.<br>(no debugging symbols found)...done.<br>"/var/lib/systemd/coredump/core.opensips.993.b6ac8a71177a49cd8238e22ba265c6e9.16129.1594410164000000.lz4" is not a core dump: file format not recognized<br>Missing separate debuginfos, use: yum debuginfo-install opensips-2.4.8-1.el8.x86_64<br><br>I am running Centos 8.
